Given our finding with respect to the lead agency issue, Cal-Am should undertake preparation of a Proponent's Environmental Assessment for the Coastal Water Project as soon as possible. Given the interest by the County and the water supply issues facing the County as a whole, not just Cal-Am's customers, we direct Cal-Am to thoroughly explore opportunities for partnerships with other regional water supply entities as it prepares its PEA and to incorporate such partnerships into the project if appropriate.
